Aerosmith guitarist Joe Perry -- rock god, and hardcore scofflaw ... after bombing the band's logo on a building without the owner's consent ... all for a guerrilla marketing campaign.

TMZ has obtained photos and video taken very early Thursday morning of Perry tagging the wall of a production studio in downtown Los Angeles.

Our street art sources tell us Perry contacted a local graffiti artist named RISK to scout locations where they could plaster the Aerosmith logo and "Let Rock Rule" ... the name of their upcoming tour.

Problem is it caused a major issue for the owner of the building -- who tells TMZ they were slated to do a photo shoot on the wall Perry defaced.

The owner says he's a big Aerosmith fan so he's not pressing charges -- but he had no idea about Perry's tagging mission ... and was forced to push back their client's shoot so they could paint over the wall ASAP (below).

Law enforcement sources tell us if Perry is caught in the act -- marketing or not -- he will be arrested for vandalism.

We reached out to Perry ... and in true rockstar fashion he said, "let the music do the talking."

EXCLUSIVE

Michael Jackson's people have just thrown Britney Spears, George Michael, Van Halen, Aerosmith and other big names under a big tour bus, because MJ's people have just labeled them hard-core drug abusers just to make a point in a lawsuit.

Here's the deal. Lloyds of London has refused to pay benefits under an insurance policy that AEG took out in case MJ was not able perform for the "This Is It" tour. Lloyds rejected the claim on grounds Michael and AEG defrauded the company by failing to fess up that MJ was a drug abuser.

Now the bus. The Michael Jackson Company (MJC) sued Lloyds, demanding payment. MJC claims in public documents -- obtained by TMZ -- that a number of artists, including Britney, George, Van Halen, Aerosmith, Kings of Leon, AC/DC, Johnny Hallyday and Whitney Houston all were known drug addicts and all of them applied for similar insurance to Lloyds.

MJC wants to see how the other rock stars were treated to determine if Michael is being singled out unfairly.

Short story -- to make their case, they're going to tar and feather every other rock star and act in sight.

Aerosmith has cancelled a concert in Indonesia scheduled for Saturday after two militants were arrested for allegedly plotting to blow up the Myanmar Embassy.

A promoter for the show in Jakarta blamed the cancellation on safety concerns -- it's unclear if there was a direct threat to the band or the concert venue.

Cops in Indonesia said two suspected militants had been arrested in connection to the bomb threats -- and explosives were seized. According to reports, the militants are suspected of plotting to use the bombs against the Myanmar Embassy in Jakarta to protest Myanmar's treatment of Muslims.

Aerosmith apologized for the cancellation and promised to make it up to the fans there, but there was no immediate news about rescheduling.

breaking news

Steven Tyler says he "snorted half of Peru" over the course of his drug-addled rock career -- easily spending at least $5 million on cocaine before he finally kicked the habit.

The Aerosmith singer revealed the drug numbers on Australia's "60 Minutes" this week, saying he spent a fortune on booger sugar as a young rock star ... "Probably, realistically, 5 or 6 [million], easy ... You could also say I snorted half of Peru, but, you know, it's what we did."

Tyler's been open about his former drug addiction for a while now -- telling Matt Lauer back in 2011, "I needed that cocaine. I needed it." But he said it ruined him, adding, "It took my children away, it took my marriages away. I was on my knees."

Tyler sobered up in the mid 80s but later relapsed. He was diagnosed with Hepatitis C in 2003, which he believes he contracted as a result of his intravenous drug use.

Tyler's been in and out of rehab numerous times, but now considers himself sober.

Steven Tyler had a rough morning -- not only did he not know what show he was on, he also dropped an F-bomb on live television!

Tyler -- who is probably never awake at such an early hour -- performed with Aerosmith on the "Today" show this morning ... only he thought he was on a different program. Al Roker's reaction ... priceless.

Then, while Roker was giving a weather update, Tyler screamed in the background to the crowd, "Thanks for coming out, you crazy f**ks!"
